Here, some real issues from an owner of 10 years here.

1. Sunroof will leak. It's not IF, it's when. And when it does, you can either replace the seal yourself like I did (it does require tools but I'm an engineer so..) or pay thousands of euros to have the whole thing replaced by the Mercedes
2. Starters fail since they're the most exposed component at the bottom of the car and will likely get soaked everytime you drive on wet roads
3. Doors rust (factory recall and warranty issued back in the day) and they rust so hard it almost doesn't make sense to repair them
4. Boot springs get tired and won't lift the door properly after 10 years
5. headlights are very inefficient and visibility is poor - LED upgrade recommended
6. Brake booster is weak from the factory so when it gets older, it makes sense to replace it before it gets even weaker
7. All major suspension components will need to be replaced at 200k kilometers intervals. Broken springs are a thing, as well as balljoints, shocks, arms etc.
8. window motors are weak, won't lift glass at satisfactory speed after a while - it's also an indication that the alternator is giving up.
9. car is very low in the middle due to DPF filer system so you WILL bottom out if you're not careful
10. Silencer tends to rust because it's not protected. I had mine changed and the old one basically fell apart as they were removing it from the car.
11. LCD screen will die after 15 years or so. You can replace it yourself by dissembling the instrument cluster, it's pretty plug and play. Replacement costs about 50€
12. Handbrake is shit by design, when you feel like it's giving up - replace the whole assembly. It's not worth replacing part by part.

Advice - change oil every 10k kilometers, change filters MORE OFTEN than the interval, delete ERG valve and flaps and change engine map to sth more efficient.
Also - preventative care. If you hear sth's off, address it. The car will give back to you. It's a great machine. The engine is bulletproof.

I've also heard that the CVT models are shit because the transmission is very weak, only 250nm max. The manual models can handle much more, 400nm.

I have a 170, with 220k. I never have a problem. I love this car

My Experience on this car B180 year 2006 since I bought it in 2019 it was only problem of leaking oil.since it was repaired I have no problem and the km is 230, 000 I bought it with km 172000 I think it is reliable my cvt gear oil was changed once and it is shifting nice

Automatic transsmition is good, one of the best CVT. The car is comfortable and practic

Bro, amazing video. Thank you so much for complete summary of b200. I am wondering have you heard any issues for reliability? I am considering this car for my winter car here in Canada. Thank you friend.

I'm probably too Dutch to understand, but this video, that is supposed to be about the problems and weak points of the B Class, is almost completely about the good quality of the car.

The first time in this video a problem is mentioned is at 2:36, and even then only very briefly and kind of sugarcoated.

There is nothing wrong with mentioning the good points of a model, but when the title of the video states that the video is about the week points and common problems of the B Class, why not immediately start mentioning these things?

Again: maybe I am too Dutch too understand. We are very direct and we don't dance around things nore sugarcoat things. We believe that nobody benefits from saying A, while meaning B. In many cultures this Dutch way of communicating is seen as rude and inconsiderate (e.g. look at how Brits react to Max Verstappen's press conferences), and I understand that when I try to put myself in the position of someone who is from a very indirect culture. However, although I wouldn't want to go as far as stating that not being direct in communication is just as rude and inconsiderate, it's always good to try to see things from an other person's perspective.

Or maybe I will have to acknowledge that East is East, and West is West, and never the twain shall meet.

10 years and counting, I use it daily to get to work ~20 kilometers one way, it literally never died on me, not once.

[clarissasyllaba]

Your thoughts on a 2008 b200 diesel would be appreciated. I looking at a used one with 220km

[davidbarton]

Cvt gearbox boxes need attention at 100, 000 miles seems to be a common thing

[jibrail]

7g tronic will give problems with transimssion pacage so you have to fix it or replace it which will cost 1000$+ i had mine repaired i have 240k km and it was repaired before i did repair it again

[elvis]

My speed display stoped working on my b180, 2018. Does annybody else has that problem?

[Rommel-dx]

You don’t know what you’re talking about.

[corinful]

Main common problem is the vents behind rear bumper are glued in with chewing gum and start to leak turning the boot in to a swimming pool

[forrera]

Biggest problem with the B class is a bad mechanic.

Maybe its too late but i will give my recommentedion.
I have b200 cdi 2005. 670.000km and its still good. There is problem with injectors and u need to check them if you hear any unusual sound. Also problem with LCD when engine get 60 degree C LCD DIES, when engine get cooler it will come back. In my country they say here is bad diesel and it take my 11/12l on 100km in busy town and 6l on 100km on highway. I will say that its good car (i didnt say good things because everything except this is good) but you need to be careful what you buying. Also if you dont care for car u can have problem with window electric if u press button to hard, and because of speed bumpers and holes u can have problem…

[jonathanhope]

Mine is trash every time i fix one problem a new one comes up. Not very reliable.

[antidiusalex]

I don’t know what’s wrong with my b class after I got better problem now I can’t even switch it on

[kaliteoman]

CVT automatic gearbox always gives speed sensor fault. Not good.😢

[Rjl]

I owned the 180 CDI from 2006 to 2008, awful CVT gearbox, unreliable, did not work properly, and Mercedes had been waiting 2 years before telling me that I had to change the defect CVT!!!! so I bought a E87 118d BMW in manual shift!

[Gasmaska]

So many BS information in this video I stopped watching mid video.
